System synthesis segment level

In order to further improve the solubility of uronium salts and to eliminate any absorbance in the range 300-350 nm as this will improve Fmoc-assisted monitoring of peptide synthesis, uronium compounds derived from the oxo-pyridine system have been synthe-sized. TPTU (16) has been recommended for segment condensations (low epimerization level),and couples A-methyl amino acids more efficiently than TBTU.f Uronium salt TOPPipU (40), although causing substantial epimerization, is unique in possessing significantly enhanced solubility (1.5 mol-L in DMF).t l... [Pg.559]
